[PATCH v4 01/15] device property: Move fwnode_handle_put() into property.h

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

By having this function as static inline in the header, the compiler
is able to see if can optmize the call out if (IS_ERR_OR_NULL(fwnode))
This will allow a simpler DEFINE_FREE() call in the following patch.
